Abstract: An apparatus and method for removing weeds from an aesthetic mulch garden using an autonomous battery-powered differential-wheeled robot is disclosed. The boundary of the domain of said aesthetic mulch garden is predefined by the user and said robot is confined to patrol within said domain. The robot searches for weeds using machine vision which seeks colorimetric contrast between weeds and mulch and undergoes a novel randomized reflective trajectory to patrol said domain. An independent collision avoidance system allows said robot to avoid interaction with non-weed objects. Said robot has a central processing unit (CPU) receiving input from said machine vision system which positions a device for weed extraction and controls said extraction. A built-in suction system and receptacle is incorporated in said robot to maintain the weed extraction device clean and ready for operation while storing extracted weeds for later disposal.

Abstract: A lock assembly (1) including a main body (4) and a protruding member (5). The protruding member (5) is biased to normally protrude outwardly of the main body (4) by a biasing component (6), which is formed of rubber or like material. An operating mechanism, operated by a key (9) effects movement of the protruding member (5) between a protruded or locked position, and, a withdrawn or unlocked position.

Abstract: A display table movable between a standing position and a folded position is disclosed, comprising a back, a table top pivotable with respect to the back, a middle leg pivotable with respect to the back, and a brace pivotable with respect to the back and slidably received in the middle leg. In the standing position the brace engages the middle leg so as to resist movement of the middle leg with respect to the brace.

Abstract: A cable gland assembly for an electric cable having a sheath enclosing at least one conductor core is described, the assembly comprising a body and a barrier sleeve (4) locatable in the body wherein, in use, the at least one core extends through the body and the sleeve (4) and a hardenable compound is disposed in the sleeve (4) filling the sleeve and surrounding the at least one core, wherein the sleeve (4) comprises a resilient or elastic material.

Abstract: A removable cap is provided to cover temporarily the end of a cable during assembly of a cable gland to protect an elastomeric seal from contact with sharp conductor cores.

Abstract: The female part of an underwater electrical connector has inner and outer chambers containing non-conductive fluid. Each chamber has an opening sealed by a respective spring loaded ball in the unmated condition of the connector and by a contact pin of the male part in the mated condition of the connector. The balls are displaced transversely to the direction of movement of the contact pin to engage the contact socket and automatically re-seal the openings when the contact pin is withdrawn.

Abstract: An insulation piercing earthing ring for a gland termination to provide earth continuity between an electrically conductive gland body and an electrically conductive inner sleeve of an insulated cable or pipe has a flat annular washer for locating against the end of the cable or pipe with at least one contact finger extending from the periphery of the washer to surround the cable or pipe and terminating in an inwardly directed projection for piercing the insulation. The contact finger extends axially and radially outwards from the periphery of the washer in the undeformed free state and is deformed radially inwards by engagement with a tapered entry portion of the gland body causing the projection to pierce the insulation and contact the electrically conductive inner sleeve.
